代码说明:

  Fit time series Q(t) to a logistic function. Inputs (vectors of same size): t (time) & Q Outputs: Qpre (logistic model fit to data) and three independent parameters: thalf, Qinf, and a, describing the logistic Q(t) = Qinf/(1 + exp(-a*(t-thalf))) Qinf is value as t --> infinity thalf is time of symmetric inflection point a is time decay constant Written by James Conder, Southern Illinois University, Oct. 2010

    这个例子将产生并显示pi/2 DQFSK系统中的一些重要信号,仿真这个系统并产生图形输出的MATLAB程序在文件夹中给出。在MATLAB的命令提示符下输入程序名c8-pi4derno后,会绷现一个菜单,用户可通过这个菜单选择以下七个选项中的一个(产生一个图形后,击空格键会显示菜单以便作另一个选择) 1.滤波前的pi/4 DQPSK信号星座图 2.滤波前的pi/4 DQPSK眼图- 3.滤波后的pi/4 DQPSK信号星座图 4.滤波后的pi/4 DQPSK眼图 5.滤波前的同相和正交信号 6.滤波后的同相和正交信号 7.退出程序(返回MATLAB命令提示符) 读者应该仔细研究文件夹中的内容,因为它阐明了很多常见的后处理过程,而且,产生各种图形的代码可用于其他仿真程序的后处理器。 (It is very difficult to describe the MATLAB procedure in english.)

    在进行车牌识别的预处理过程中,如何有效地提高车牌图像质量是一个关键,这一步处理的好坏将直接影响到后面车牌识别的效果。 本文重点研究直方图修改技术增强图像方法在车牌识别预处理中的应用,给出了直方图修改技术的原理,以及直方图均衡化、规定化和对比度调整的原理,最后用MATLAB来实现车牌图像增强的效果。(License Plate Recognition in the pre-treatment process, how to effectively improve the image quality license plate is a key to dealing with the merits or demerits of this step will directly affect the effectiveness of the back license plate recognition. This article focuses on the image histogram modification method to enhance license plate recognition in the pre-processing of applications, given the principle of histogram modification techniques, as well as histogram equalization, contrast adjustment provisions and the principles of using MATLAB to achieve the final vehicle the effect of brand image enhancement.)
